KEY.

SPECIFICATION forming part of Letters Patent No. 399,094, dated March 5, 1889.

Application tiled October 15, i888A To 1U 'whom 1215 may concern;

Beit known that I, OSCAR STODDARD, a citizen of the United States, residing at Detroit, in the county of llIayne and State of Michigan, have invented certain new and useful Improvements in Door-Keys; and I do declare the following to he a full, clear, and exact description of the invention, such as Wi ll enable others skilled in the art to which it ap pertains to make and use the same, reference lacing had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a partoi this specification.

This improvml key is designed Afor the doors of residences havin g what is knoyvn as moruse-locks.

The construction of this key is such that it 1 cannothe tampered with when left in the lock hy inserting a Wire or tool through the l keyhole from the outside of the door for the y purpose ot' turning the key in the look and thereby unlocking the door.

The key is so constructed that a portion remains lixed in the key-hole of the lock when locking or unlocking the door. This stationary portion fills the outer opening or escutchn I eon ol the key-hole, thereby preventing the insertion ot' any tool through the key-hole when the door is locked and the key is inthe lock.

The essential features ot' this invention will 4 he ullyhereinatter set forth, and pointed out i particularly in the claim. 1

In the accompanying drawings, forming a part of the specifica-tion, Figure l is a side plan of an ordinary door-lock, showing the turned portion of the key by dotted lines when the door is locked, showing also the stationary portion of the key in the key-hole. Fig. 2 is a side plan of my improved key. Fig. 3 is a slight modification of same; Fig. l is a vieiv, partly in section, showing the parts of the .key detached and their relative position.

In the drawings, I. represents the loekafaso, and d the key-hole therein, in which n reprcsents the portion of the key that remains stationary as the key is turned in the lock to move the lock-holt, as in locking and unlockn ing the door. The shank S of the key is proA keyhole.

Serial No. 288,169. (No modelJ vided with a slot or opening, f, which leads from near the annular shoulder h to about the center of the stein or shank. Communicating with the oblong opening f, and extending through the head I-I of the key, is an opening or hole, t, which hole receives the metal rivet Z. (See Fig. 4.) Said rivet has the head a', which lies Within the opening f, as shown in Figs. 2 and 3.

D represents the common lock-operating wing to thekey, which may he of any desired shape.

Mounted on the outer end oi' the rivet Z, which projects through the head of the key, is an auxiliary Wing, n, its forni in cross-seetion coinciding with that of the head H and v operating-Wing D of the key. The auxiliary Win g a is provided With the hole i in its outer ond, being countersunk at (t. Said hole registers with the hole f in the head of the key.

' The rivet Z is upset at e, thereby holding the auxiliary wing in position, and hy the upsetfting ol' said rivet the desired tension may be obtained, so as to hold the auxiliary Wing in its normal position, so as to register with the Wing D ot the key, yvherehy when the key is passed into the key-hole of the leek it will enter freely, allowing the auxiliary Wing n to pass into and till the key-hole on the opposite tace of the lock, and to remain therein as the halanee ot the key is rotated to move the lockholt, lor the purposes hetore stated,

In 3 I show the ning n provided with a rear extension or prong, Y', which allons the wine' D to rotate ahove it. rlhis irene s l i acts as a guide to prevent the wing ln from catching when withdrawin the key from the This `feature is not essential, for the rea-son that the Wing n "will remain in its proper position il the rivet Z is properly tightened by the upsetting of the end at e, as before stated. This arrangement affords means of giving to the auxiliary Wing 'n a proper degree of pressure or friction, whereby the parts will work complete, and the auxiliary win g is i'irml y and substantially secured to the head of the key.

Having thus fully set forth my invention, what I claim as new, and desire to secure by Letters Patent, is-

.ai door-key comprising the following ele IOO ments: the shank havin g the opening therein, the head and Jhe auxiliary Wing, its outer e116` the head having the annular shoulder and being upset, as and for the purposes specified. 1o Wing, said parts formed integral, the hole l In testimony Whereofl affix mysignature in passing through the head and communicating presence of two Witnesses. 5 with the opening in the shank, the auxiliary I wing, its form in cross-section coinciding t l Titnessesr OSCAR STODDARD.
